First, let your widget state class implement SingleTickerProviderStateMixin
.
Secondly, define an AnimationController
and don't forget to dispose it. If you are not yet using null-safe, remove the late
keyword.
late AnimationController _controller;@override
void initState() {
_controller = AnimationController(
duration: const Duration(milliseconds: 5000),
vsync: this,
);
super.initState();
}@override
void dispose() {
_controller.dispose();
super.dispose();
}
Then wrap your Widget
with RotationTransition
.
RotationTransition(
turns: Tween(begin: 0.0, end: 1.0).animate(_controller),
child: Icon(Icons.stars),
),
Finally, call methods on the AnimationController
to start/stop animation.
- Run the animation once, use
.forward
- Loop the animation, use
.repeat
- Stop immediately, use
.stop
- Stop and set it back to original rotation, use
.reset
- Stop and animate to a rotation value, use
.animateTo
